The DS1337S+ Real Time Clock (RTC) combines battery-backed RAM and crystal-controlled timing in one package to always provide correct date and time information in a microprocessor-based system. This versatile and efficient RTC is used in applications including PC add-in boards, PC peripheral clocks, embedded systems, and consumer electronic products. It allows users to receive accurate date and time information while conserving current as well as avoiding costly software development requirements.The main features of the DS1337S+ Real Time Clock include: a 24-hour timekeeping, daylight savings time corrections, leap year corrections, 4-byte Date/Time RAM registers, a watchdog timer, and CMOS RAM for storing customized parameters.The DS1337S+ has two modes of operation. In one mode, the user has the complete control over the RTC and has the power to set and reset the time and date. The other mode does not require the presence of the user, as it automatically increases the time every second and stores it in RAM. One of the main advantages of using a real time clock like the DS1337S+ is that it is capable of very accurate timing. The crystal-controlled timing module provides clock accuracy of 2.5 parts per million that is capable of keeping track of time within 100 milliseconds at any given hour. The DS1337S+ can be used in a wide range of applications. It can be used in PC systems as an add-on board, to count down scheduled start-up and shut down times, to store system log data, and to store alarm settings. In embedded systems, the real time clock can be used as a sequence controller and timer while also collecting date and time information. Finally, it can be used in consumer electronics such as TV set-top boxes and digital audio players to keep track of configuration settings and schedules. The working principle of the DS1337S+ is relatively simple. The RTC includes a number of registers which store the current time and date settings. These registers are clocked out to a microprocessor at intervals of one second. The microprocessor then reads the registers and sets the time and date accordingly on the system. The DS1337S+ keeps accurate time using the crystal-controlled oscillator module. This module uses a quartz crystal as its resonant element and is temperature compensated. The crystal oscillator module is responsible for generating a high-frequency signal of 1 Hz frequency. This 1 Hz signal is then divided down to generate a 0.2 Hz (32.768kHz) signal. This signal is then used to keep track of time and date information in the DS1337S+ RTC. In summary, the DS1337S+ Real Time Clock is a versatile and highly accurate real time clock designed to provide correct date and time information to microprocessor based systems. The device offers two modes of operation and can be used in a wide range of applications. The device works by generating a 0.2 Hz (32.768kHz) signal which is then used to keep track of time and date information.
